JavaScript Positive factorial

🔢 Factorial Calculation: Functional vs. Procedural This project demonstrates two distinct approaches to calculating the factorial of a number ($n!$) in JavaScript. It highlights the evolution from traditional loops to modern, concise array methods.

📂 File Includedfactorial.js: Contains two functions that calculate the factorial of a given integer (in this case, 7).

🧠 Core Concepts CoveredModern

Functional Approach (factorial):Array.from(): Used to generate a sequence of numbers from 0 to $n$..slice(1): Removes the leading 0 to prevent the final product from being zero..reduce((a, b) => a * b): A powerful high-order function that "reduces" the entire array into a single product by multiplying each element.

Traditional Procedural Approach (fac2):for Loop: Uses a standard incrementing loop to multiply a running total (fac2) by the current index.Initialization: Demonstrates starting the product at 1 to ensure correct multiplication.
